BoB display at St. Athan in early 50's - mainly remembered for a fatal accident when a Havard spun into the ground. I also remember them having to push the crowd line back to allow a Valiant to taxi out. The left wing tip still overhung the crowd.
For some reason I have also never forgotten watching an F86 pilot disappearing into the air intake as he did his preflight checks.
There used to be superb funfairs and demonstrations in the hangars. I particularly remember two model Hunters whirling round on a piece of string, driven by compressed air. For 6d. you could fly them by controlling the air supply.
